Treatment of anogenital warts in genitourinary clinics in England and Wales.

A questionnaire on the treatment of anogenital warts was sent to 150 consultants in genitourinary medicine, 78 (52%) were returned completed. A wide range of treatments were used; podophyllin was the commonest first line treatment of multiple penile (60.3%), perianal (57.7%) and vulval (61.5%) warts. Cryotherapy was a popular choice for intrameatal warts (65.3%), small numbers of vulval warts (33.3%) and as second line therapy for penile (35.9%) and perianal (33.3%) warts. Vaginal warts were treated with podophyllin (39.7%) or cryotherapy (29.5%). Various combinations of podophyllin, trichloroacetic acid and cryotherapy were used (2.6%-24.3%) although there is no evidence this offers benefit over single therapy. Podophyllin is frequently used despite side effects, a poor clearance rate and in vaginal warts, difficult access. Initial therapy with more time-consuming procedures such as cryotherapy or electrocautery may be of benefit to selected patients.
